GAS-LIGHTING APPARATUS.

Specification of Letters Patent.

Patented July 16. 1912.

Application filed August 22, 1910. Serial No. 578,385.

To all whom 'it may concern Be it known that I, ALBERT R. \VALKER, a citizen of theUnitcd States, and a resident of the city of St. Louis and State of Missouri, have invented a new and useful Improvement in Gas-Lighting- Apparatus, of which the following is a specification- This invention relates to gas lighting apparatus and more particularly to gasolene gas pressure systems.

It has for its principal objects to secure a maximum candle power with an expenditure of a minimum of gas, and to secure certain advantages hereinafter more fully appearing.

The inventionconsists in the parts and in the arrangements and combinations ot parts hereinafter described and claimed.

In the accompanying drawing which forms part of this specification and wherein "like symbols refer to like parts whereever they occur, Figure 1' is a View partly in elevation and partly in vertical section illustrating a portable hot process gasolene gas apparatus embodying my invention; Fig. 2 is a section. on the line 22 of Fig. 1; Fig. 3 is a fragmentary elevation of a modified construction and arrangement. of lighting arms; and Fig. 4 is a similar view showing a further modification of the lighting arms.

As illustrated in the drawings, theapparatus comprises what is known as a hot process gasolene. gas generator which is mounted in a. suitable casing or housing 1. In the lower portionofthe housing is a tank 2 which containsgasolene under pres sure. Leading from the tank 2 is a pipe or tube 3 of small diameter. This pipe 3 is connected to the lower end of a v rtical tube 4 which is mounted in a box or frame 5 in. the upper portion the housing 1. Communication between the pipe 3 and tube 4 is controlled by a. suitable valve 6 so that the flow of liquid into the pipe 4 may be regulated. Communicating with the upper portion of the pipe 4 is a horizontal tube or pipe 7 whose outer end extends through the casingl and is open to the outside atmosphere. The outer end of this pipe 7 is preferably covered with wire gauze 8. A bypass or return pipe 9 is connected at one end to the pipe 4 above the air pipe T and at its opposite end toa' gas burner 10 which surrounds the pipe below said air pipe 7; and mounted on the pipe-41 above the the pipe 3.

burner 10 is a baflle'plate or deflector 11.

Surrounding the pipe 1 below the burner 10 is a cup or receptacle 12.

The arrangen'icnt of the parts above described constitutes anordinary hot process gasolcne gas generator. In its operation, the tank 2 is supplied with a quantity of gasolene. The tank is then pumped up with air pressure and the valve 6 is opened to admit the gasolene into the pipe J. through- A quantity of gasolene, alcohol or other suitable oil is poured into the receptacle 12 and ignited. The flame from the burning oil in the receptacle l2heats the pipe 4 and vaporizes the gasolcne which enters the same, and the vapor mixes with air which is drawn in through the tube '1', said mixture of vapor and air passing into a tubular upright or post 13 which mounted on the casing 1 and is connected at its lower 'end with said pipe 4. A portion ofthe gas thus generated is conducted through the return pipe 9 to the fuel burner 10 which is ignited and keeps the tube a continually heated after the oil is burned out of the receptacle 12.

Extending laterally from the upper end portion of the tubular upright or pipe 13 are a pair of horizontal pipes or tubular arms 14, 15. Dependingfrom each of these pipes 85. area series of nozzles 16 on the lower ends of which are secured inverted incandescent gas-light mantles l7. Mounted on the up-- per horizontal tubular arm or pipe 14. is an angular reflector 18. This reflector is pref erably secured to said horizontal pipe 14 by brackets 19 having sleeve portions 20 which are loosely fitted over the pipe and secured in place by set screws 21. On the lower horizontal pipe 15 is a similarly mounted concave or selnicylindrical reflector 22. By pivoting the reflectorsxon the pipes l-l and 15 as shown, said reflectors may be tilted to different angles so as to" reflect and concentratethc light to a restrictedarea for too photographic purposes or other cases where it is desirableto have stron light. By tho arrangement. of a horizonta? row or battery of inverted lights substantially as shown. advantageous results are obtained which have heretofore been accomplished only through the medium of'an arrangement of lights which is more'com plicated and consumes a greater amount of gas. In fact. satisfactory results in photographing by artificial light have generally been successfully accomplished by the use of a horizontally disposed electric tube.

some cases, a greater number of the horizontal arms may be provided.

Obviously, the apparatus admits of considerable modification withoutdeparting from my invention. Therefore, I do not Wish to be limited to the specific construction and arrangement shown.

hat I claim is:

l. A portable gas lighting stand comprising a base, a standard thereon, a horizontal arm on said standard, a series of closely associated burner elements depending from said arm, inverted gas mantles on said burner elements, and a reflector pivoted on said arm in cooperative relation to all of said burner elements.

2. A portable gas lighting standcomprise iug a base, a standard thereon, a multiplicity of horizontal arms on said standard. a series of closely associated inverted incandescent gas burners on each of said arms, and separate elongated reflectors pivoted on the respective arms in cooperative relation to the series of burners thereon.

In a gas lighting apparatus, a portable stand comprising a base, a standard thereon, a pair of horizontal pipes mounted on said standard in vertical alinement, each of said pipes having a multiplicity of closely asso ciated pendent incandescent gas burners thereon, a reflector pivotally mounted on the uppermost pipe and extending throughout the length of the series of burners thereon, said reflector having a portion overhanging said pipe and a portion depending at one side thereof, and a. concaved reflector pivoted near its upper edge to the lower pipe and extending throughout the length of the series of burners thereon,
